Final answer:
In Excel, use the 'Use Relative References' button in the Developer tab before recording a macro to ensure it uses relative cell references, allowing the macro to adjust cell references relative to the location it is run.
Step-by-step explanation:
To use a relative cell reference in a macro, you should start by clicking the 'Use Relative References' button before recording your macro commands. This is because macros in Excel record your actions exactly as you perform them. By default, Excel records macros with absolute references. If you want your macro to use relative references (meaning the cells referenced in the macro adjust relative to where you run the macro), you need to click the 'Use Relative References' button found in the Developer tab of the Ribbon. If you forget to do this before recording, you will indeed need to modify the macro in the VBA editor. Pressing F4 or holding the shift key down while recording the macro does not serve the function of setting relative references.
